6x+1/2xy=3 please help im confused
Answers
y = 90 + -45x + -10x2 + 5x3
-6x + -3x = -9x y = 5(18 + -9x + 1x2 + -3x2 + x3) (-2 + x) * (3 + x) y = 5(-2(3 + x) + x(3 + x))(-3 + x) y = 5((3 * -2 + x * -2) + x(3 + x))(-3 + x) y = 5((-6 + -2x) + x(3 + x))(-3 + x) y = 5(-6 + -2x + (3 * x + x * x))(-3 + x) y = 5(-6 + -2x + (3x + x2))(-3 + x)
y = 90 + -45x + -10x2 + 5x3=
10 15
115+-45=70
X=70
Step 1: Factor out variable x.
x (y+12/2)=3
Step 2: Divide both sides by (y+12/2.
x(y+12/2) 3
------------- = ---------
y+12 y+12
----------- ----------
2 2
Then your answer would be 6
x= ---------
y+12

Step-by-step explanation:
In this question, we are asked to select the expressions that represent the number of vacation days per x days worked.
Now, to do this, what we simply first do is to get the number of days to takes to get one paid vacation. In the question , we are made to know that he gets 3 days paid vacation for 60 days of work. The number of days to get a single paid vacation would thus be 60/3 = 20 days. This means she gets one paid vacation in 20 days.
Now, we are told after working for x days, how many paid days vacation does she get. To know this, what we do is to first know the number of 20 days in x days. That would simply be x/20. This is the number of vacation days she gets in x days.
now, we check if there are similar options to this.
D is also correct. This is because x/20 is same as 0.005x

Answer:
Width = 57cm
Step-by-step explanation:
The area of a rectangle can be found by using the formula:
Area = Length * Width
Since we know that the area is 4275cm² and the length of the painting is 75cm, we can plug these into the above equation to solve for the width.
Area = Length * Width
4275cm² = 75cm * Width
To find the width, we can simply divide both sides by 75 so that the width measurement is isolated:
Width = 57cm
To verify this, we can multiply the length and width to see if the area equals 4275cm²:
75cm * 57cm = 4275cm²

Step-by-step explanation:
Standard equation of a line with slope, m and y - intercept b is y = mx + b.
Clearly. for the second equation has a different coefficient for x.
a ) The coefficient for x , is the slope of the line.
Though the y - intercept for each equation is same = - 4.
For example :
Expression A = 2 , when x = 1
Expression B = 8 , when x = 1
Expression C = 2 , when x = 1
b) From above :
c) Expression A and C are equivalent because the coefficient of x
is the same for A and C.

In order to get the constant of variation, you can either make a linear equation that relates x and y in which the slope is the constant of variation
LINEARIZING
x = 3y
the slope of the equation is 3 and therefore the constant of variation is 3
